Poly(rA) • Poly(rU) with Ni2+Ions at Different Temperatures: Infrared Absorption and Vibrational Circular Dichroism Spectroscopy
Autor: H. Wieser, Yu. P. Blagoi, Valery Andrushchenko, J.H. van de Sande
Publikováno v: Journal of Biomolecular Structure and Dynamics. 19:889-906
Phase transitions were studied of the sodium salt of poly(rA).poly(rU) induced by elevated temperature without Ni(2+) and with Ni(2+) in 0.07 M concentration in D(2)O (approximately 0.4 [Ni]/[P]). The temperature was varied from 20 degrees C to 90 de

Dimers of phenol in argon and neon matrices
Autor: Victor A. Karachevtsev, E. D. Radchenko, A. M. Plokhotnichenko, Yu. P. Blagoi
Publikováno v: Low Temperature Physics. 27:666-675
The IR absorption spectra of phenol molecules in solid rare gas matrices of argon (10–12 K) and neon (4.5–5 K) are investigated at molar ratios of phenol:matrix of 1:1000 to 1:30 in the frequency range 400–4000 cm−1. Bands of dimers and large
